Description

A kind of personalized earphone applied to sense of hearing sense organ exception people
Technical field
The utility model is specifically related to a kind of personalized earphone applied to sense of hearing sense organ exception people, belongs to daily necessities skill Art field.
Background technology
It is estimated that autism spectrum disorder（ASD）Illness rate have in there are 160 children in the whole world 1 suffer from ASD （The World Health Organization：WHO, 2017）.U.S.'s ASD illness rates grow steadily, and mainstream school is in Hong Kong in 2010 also with 20% Speed increases.The exception studies have shown that autism children is felt.70% ASD children have found their sensitivities to auditory stimulation Property is higher.Statistics display, it is necessary to formulate a strategy or policy, or even support them to cope with this challenge.
ASD children are found to use Heal Thyself strategy, including covering ear, even self injury of crying and screaming.These behaviors Influence their daily life, social life and study.Acoustically improve ambient sound for reinforce ASD treatment and Children are important.Earmuff or earplug can generate positive influence to the reaction sex-related issues of ASD children's auditory stimulations.Drop It makes an uproar earphone（NC earphones）It will be their potential solution.However, ASD infants are to the sensibility of auditory stimulation and differ. Their study can be reinforced to preschool and primary school period ASD children's auditory stimulation sensibility adjustment.This is conducive to them Future development under acoustic enviroment.Noise reduction system for ASD children's development personalizations is most important.
Utility model content
The technical problems to be solved in the utility model overcomes existing defect, provides a kind of applied to sense of hearing sense organ exception people Personalized earphone, can be adjusted by Bluetooth technology, serve as general hearing aid, can be used as bluetooth headset and hearing-aid function It makes a phone call together, bluetooth headset can be served as, for listening to music hearing-aid function, using noise reduction technology, digital signal processor (DSP) noise reduction technology eliminates noise reduction technology in the audible sound frequency response of different people and the passive noise of earphone mechanical structure, It can be used for assessing susceptibility of each ASD patient in particular frequency range by Bluetooth technology, can effectively solve background skill The problems in art.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution：
The utility model provides a kind of personalized earphone applied to sense of hearing sense organ exception people, including microphone, preceding storing Big device, A/D converter, bluetooth radio circuit, DSP module, D/A converter, post amplifier and loud speaker, the microphone are used In pickup environmental noise, and by information conveyance to preamplifier, the preamplifier is used to environmental noise being changed into number Word signal is input to DSP module, generates de-noising signal inside the DSP module, this signal is converted to original noise, described DSP module turns de-noising signal to do analog signal, then signal is amplified in loud speaker, the DSP module via post amplifier It is connect with bluetooth radio circuit.
As a kind of optimal technical scheme of the utility model, the microphone picks up noise and sends it to preceding storing Big device, the preamplifier generate identical reverse phase waveform and send back to microphone.
